What H-Reason does

H-Reason provides source-first FPF-aware reasoning for ambiguous engineering, management, architecture, specification, or project questions in a Haft project. Use it when no narrower Haft capability is current; ordinary reasoning stays conversational and binding actions remain manual.

H-Reason is cataloged under AI Engineering on DirSkills. H-Reason comes from a repository tagged ai-agents, ai-coding, anthropic, claude and claude-code.

Documentation

README

Excerpt

h-reason — Source-first FPF entry

Contract truth: source-native FPF Query and typed-memory resolve, neighborhood, and recall are V9 CONTRACT capabilities. Source, schema, skill, or local-test presence is not installed-runtime proof and does not establish Pi host parity. A readiness claim requires current EXACT-CANDIDATE EVIDENCE from P14 tied to one exact candidate; RC or release status additionally requires release authority. Pi support is an experimental compatibility carrier; stable host parity is not proven. Do not infer CURRENT PRODUCT status from contract inclusion or evidence alone.

This is the opening of the README. Read the full README on GitHub.
